I liked riding 27" tires on road bikes. I even miss them. However they went by the wayside before the turn of the Century and 700C's are the favored now for road bikes.

As a result you see all the new tire tech and high quality tires only marketed as 700C's or what ever the normal size is for other types of bikes sold today.

So you might think about that some. I got rid of my favorite ride 10 years ago because the choice of 27" road tires was so limited.
